Wow. First off, thanks for replying this much to me. I do understand that there is way more information now that I needed.
My main problem was that I was using the automatic option... I thought that it could have done the job by itself without too much adjustment.

I lowered down the ISO to 200, I am in a basement without too much lightning and that did the job, my subject is definitely sharper and clearer. The white background, this is another issue and again, I do understand that without good lightning, I won't be able to do much.

Software will be there to help me. I will continue to play around with the settings, take the same pose but with different settings then compare them.
